Aventurine

$2.00

One  1-2" aventurine specimen 

 Aventurine is a variety of quartz with inclusions that can cause it to have a brilliant optical effect.

Nearly opaque, some translucence can be seen, especially when backlit. Inclusions in the quartz can appear as sparkles from within, an effect called aventurescence.

Since pure quartz is colorless, these inclusions also provide coloring. By far, the most common color of aventurine is green. This sample is considered purple aventurine and its color comes from lepidolite—a lithium- rich mineral that forms purplish-silver mica.

Aventurine’s Mohs hardness depends on the type and proportion of inclusions, but it is typically around 6.5, which is just below the hardness of pure quartz, so it may not leave a mark on a streak plate.

The name aventurine is Italian for “by chance” and it was named after a similar looking sparkling glass which had been created by mistake.
